HAY-PRESS.

Specification of Letters Patent.

Patented June 5, 1906.

Application filed May 8,1905. Serial No. 259,409.

To all whom, it may concern:

Be it known that I, CHARLEY E. DAVIS, a citizen of the United States, residing at Aurora, in the county of Lawrence and State of Missouri, have invented certain new and useful Improvements in Hay-Presses, of which the following is a specification.

The object of this invention is to provide a novel form of hay-press of simplified construction and which may be made ver cheaply, at the same time involving a pecu iar arrangement of parts designed particularly with reference to securing the greatest amount of compression in the baling operation.

In the broad contemplation of the inven tion the baling-chamber of the press is composed of sides, and cam means is utilized for actuating the sides of the chamber to reduce the size of said chamber and eflectively compress the material which is being baled in the press.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for-effecting the result reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a vertical transverse sectional view of a press embodying the invention. Fig. 2 is a side elevation, partially broken away and partially in section. Fig. 3 is a detail plan view of the vertically-movable bar and operating cam-lever carried thereby. Fig. 4 is a side elevation of the parts in Fig. 3. Fig. 5 is a detail perspective view of one of the actuating-blocks.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

In the practical embodiment of the invention the press comprising the same has the usual baling-chamber 1, provided with the sides 2, the bottom 3, and the top 4. The ends of the baling-box, of which the members 2, 3, and 4 form a part, are received by frames consisting of a lower horizontal bar 5, side bars 6, which preferably comprise threaded rods, and an upper horizontal bar forming a head 7, through which the side pass. Arranged beneath the head 7 of each of the frames in which the ends of the baling-box are received is a horizontal vertically-movable bar 8, also having openings in its ends, through which the rods 6 pass. The bar 8 is arranged above the top 4 for actuating the sides 2 of the baling-cham ber 1. The sides 2 of the baling-chamber are provided with cams 9 upon the outer faces thereof, and these cams may be formed by the use of wedge-shaped blocks riveted or otherwise attached to the sides 2, as may be most desirable in the actual manufacture of the presses. The cams 9 are engaged by actuating-blocks 10, carried by the bar 8 and slidable vertically in contact with the sides 2, exterior thereof. The blocks 10 are formed with cams 11 to engage the cam members 9 of the sides 2, and sald blocks are movable between the sides 2 and the rods or side members 6 of the frame receiving the ends of the baling-box. Extensions 12 project upwardly from each of the blocks 10, and the upper extremities of these extensions are threaded and passed through openings in the bar 8, by which the blocks 10 are actuated. Nuts or similar members countersunk in the upper and lower sides of the bar 8 may be used to secure the extensions 12 thereto in a substantial manner. In order that the blocks 10 will be prevented from lateral play or movement and vertically guided as they are actuated by the member 8, it is preferred that the outer side of each of these blocks be provided with a vertical groove 13 to receive the rods 6, so that the latter will form guide members to accomplish the desired results above premised. Pivoted in the head 7, and preferably at a point about inter mediate its ends, is a cam-lever 14, having the cam 15 at its lower end. The cam 15 may be formed by an eccentric disk attached to the lever 14, or said cam may be integrally or otherwise formed within the scope of the invention. The cam 15 is arranged to engage theupper side of the bar 8, so that when the lever 14 is forced downwardly the bar 8 will be forced in the same direction, so as to impart downwardmovement to the blocks 10. By using the lever 14 and the cam devices 15 it will be noted that immense power may be brought to bear in forcing the blocks 10 downwardly to compress the material in the baling-chamber 1 at the sides, and when the member 8 is actuated by the lever 14 said member arranged above the top 4 of the chamber 1 will compress the material in the chamber 1 thoroughly. A toothed segment 16 is attached to the head 7 of each of the end frames of the baling-press, and this segment is adapted to be engaged by a spring latch-piece 17, oper- IIO ated by a handle 18 upon the lever 14. The latch 17 may be of any suitable construction and is designed to lock the lever or levers 14 in the lowermost position after the material in the chamber 1 has been compressed.

Specifically describing the operation of the press, the material, such as hay or the like, having been placed in the baling-chamber 1, the lever 14 is forced downwardly, moving the member 8 and the blocks 10 in the same direction. As the blocks 10 are forced downwardly the cams 11 thereof ride down the cams 9 of the sides 2, forcing the latter toward each otherin a manner readily apparent. The lever 14 may now be locked in its downward position and the bale tied. If desirable, one or more of the cam-levers 14 maybe utilized in actuating the arts, as heretofore described, and the detail eatures of construction of the invention may be changed in various ways. The usual follower 20 may be mounted for movement in the baling-chamber, as is customary in presses of this class.

Having thus described the invention, what is claimed as new is 1. In a baling-press, the combination of a baling-chamber embodying a movable side, cams upon said side, cam-blocks arranged for cooperation with the cams, and means em.

bodying a cam for actuating the cam-blocks.

2. In a baling-press, the combination of a baling-box embodying movable sides, a bar, cams upon the sides of the baling-box, sliding cam-blocks carried by the bar aforesaid for cooperation with the cams of the sides of the baling-box, and means for actuating the bar to simultaneously actuate the cam-blocks.

3. In a balingpress, the combination of a baling-box embodying movable sides, a bar, cams upon the sides of the baling-box, camblocks carrried by the bar aforesaid for cooperation with the cams of the sides of the baling-box, and a cam arranged for engagement with the bar to actuate the same.

4. In a baling-press, the combination of a baling-box embodying a bottom and sides, a frame arranged to receive said baling-box and including side members, cams upon the sides of the box, and cam-blocks slidably mounted between the sides of the box and the side members of the frame aforesaid.

5. In a balingpress, the combination of a baling-box embodying a bottom and sides, a frame arranged to receive said baling-box and including side members, cams upon the sides of the box, cam-blocks slidably mounted between the sides of the box and the side members of the frame aforesaid, and a bar connecting the cam-blocks for simultaneous operation.

6. In a baling-press, the combination of a baling-box embodying a bottom and sides, a frame arranged to receive said baling-box and including side members, cams upon the sides of the box, cam-blocks slidably mounted between the sides of the box and the side members of the frame aforesaid, a bar connecting the cam-blocks for simultaneous operation, and a cam-lever for actuating the connectingbar aforesaid.

7. In a baling-press, the combination of a baling-box comprising movable sides, aframe arranged to receive the baling-box and embodying side members and a head connecting said members, cams upon the sides of the baling box, cam blocks slidably mounted between the side members of the frame aforesaid and the sides of the baling box, a bar arranged beneath the head of the frame and connecting the cam-blocks for simultaneous operation, a cam-lever pivoted to the head of the frame and engaging the connecting-bar of the blocks for actuation thereof, and a lock device for cooperation with the cam-lever.

In testimony whereof I affix my signature in presence of two witnesses.
